Yup, Beta 52 and D112 are pretty much standard issue bass drum mics...I prefer the 52.
If you can, try getting a Beta 91 too and putting that inside and then combine with other mics...
Another suggestion though....far and away my favourite bass drum mic - a Sennheiser MD 421. Mega fat punch; not as much waayy down low response as a 52, but just a beautiful low frequency envelope with this mic. With just a touch of EQ, it can do anything. The integrated mic clip sucks but can be helped with an elastic band. Amazing on toms and floor toms too.
Find a used one!!
